How to do coefficient of variation
WebThe value of the coefficient of determination, or the variation of the Y derivative that is explained by the linear influence of X, is a metric that illustrates the extent of the independent variable's contribution to the dependent variable. R2, or the coefficient of determination, has a value between 0 and 1. WebDec 5, 2024 · F-measure. It is difficult to compare two models with low precision and high recall or vice versa. So to make them comparable, we use F-Score. F-score helps to …
